Minor Moves: Ozzie Martinez, Josh Fields

The Dodgers signed Osvaldo Martinez to a minor league contract, reports Dylan Hernandez of the Los Angeles Times. The infielder was first acquired by the Dodgers from the White Sox last July and Martinez posted a combined .489 OPS in 340 plate appearances for both clubs' Triple-A affiliates in 2012. Martinez appeared in 34 Major League games with the Marlins during the 2010-11 seasons.

The Phillies signed third baseman Josh Fields to a minor league contract, Matt Eddy of Baseball America reports (hat tip: Matt Gelb). The 29-year-old last played at the MLB level in 2010, but was once regarded as an up and coming player. He hit 23 home runs and posted a .244/.308/.480 batting line for the White Sox in 2007, though he has not come close to replicating those numbers since. Fields, a right-handed hitter who twice ranked among Baseball America's top 100 prospects, spent this past season with the Dodgers' Triple-A team. He hit 13 homers and posted a .322/.392/.488 batting line in 561 plate appearances as a corner infielder and designated hitter.
